POCKET-OILER.

SPECIFICATION forming part of Letters Patent NO. 579,795, dated March30, 1897. Application filed August 31, 1896. Serial No. 604,3 82. (N0model.)

To all whom it may concern:

Be it known that I, JOHN H. GOSS, of W'aterbury, in the county of NewHaven and State of Connecticut, have invented a new Improvement inPocket-Oilers and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a View in side elevation of one form which an oilerconstructed in accordance with my invention may assume; Fig. 2, a Viewthereof partly in elevation and partly in vertical longitudinalsection;. Fig. 3, an enlarged broken sectional View of the outer end ofthe cap; Fig. 4, a detached reverse plan view of the oiler.

My invention relates to an improvement in portable or smallpocket-oilers, the object being to provide simple and effective meansfor closing their spouts.

With these ends in view my invention consists in the combination, withthe body, spout, and cap of an oiler, of a spring-actuated followerlocated in the outer end of the cap, which is rotatable independently ofit, and containing a stopper or packing adapted to engage with the endof the spout for closing the same, whereby the cap may be rotated forscrewing it into and unscrewing it from the oiler without rotating thefollower and cansing the stopper or packing with which it is provided tobe cut out upon the end of the spout.

My invention furtherconsists in certain details of construction andcombinations of parts, as will be hereinafter described, and

pointed out in the claims.

In carrying out my invention as herein shown I employ a stopper orpacking A, of any suitable material, such as leather, and located withina sheet-metal button-like follower B, the body of which is contractednear its open end, so as to firmly retain the stopper or packingA inplace. The said follower is formed with an annular flange B, which isjust enough smaller than the diameter of the cylindrical cap C to permitthe follower to move back and forth in the outer end thereof and topermit the cap to be rotated in one direction or the other withoutrotating the follower. A spiral spring D, interposed between the outerend of the cap and the flange B of the follower, exerts a constanteffort to move the same toward the open end of the cap, which is formedwith an inwardly-projecting circumferential bead C, constituting a stopwith which the flange B of the follower engages to limit the outwardmovement thereof.

The cylindrical cap C is of usual construction, having its outer endclosed for the reception and entire inclosure of the-said follower B andthe said spring D and formed at its inner end with externalscrew-threads, which take into internal screw-threads formed within thehub E of the long tapering spout E, the said hub having externalscrew-threads taking into internal screw-threads formed within the neckF of the body F. The upper portion of the hub E is turned outward toform an overhanging knurled flange E containing a packing-Washer G,which rests upon the outwardly-turned upper edge of the neck I of thebody F".

W'hen the cap is applied to the oiler over the spout thereof, the end ofthe spout engages with the stopper or packing A before the cap has beenfully screwed into the hub of the spout, so that the follower is pushedaway from the bead C of the cap against the tension of the spring D,which is compressed and which therefore crowds the stopper or packingupon the end of the spout, so as to efiectually prevent any escape ofoil therefrom.

When the cap is removed from the hub of the spout, the spring at oncereasserts itself 0 and pushes the stopper outward until it is arrestedby the engagement of its flange with the bead of the cap. In thisconnection I particularly wish to point out that when in applying thecap to the oiler the stopper or packing carried by the follower isengaged with the spout and the spring D placed under compressionsufficient friction is developed bet-ween the stopper or packing and thespout to hold the follower against rotation with the cap, which isthereafter rotated independently of the follower until it has beenbrought into final adjustment. So, too,when the cap is removed from theoiler it is rotated independently of the follower. Byproviding for therotation of the cap independently of the follower at the time the cap isscrewed into place and unscrewed for removal I avoid the cutting out orwearing away of the packing or stopper by its rotation against the endof the spout, which is more or less sharp.

My improved means for sealing the outer end of the spout do not addmaterially to the cost of the oiler, do not interfere with the use ofthe same in the ordinary way, and are extremely eit'ective in preventingthe annoying and wasteful leakage of oil.

It is apparent that in carrying out my invention some changes from theconstruction herein shown and described maybe made. I would thereforehave it understood that I do not limit myself to the exact form shown,but hold myself at liberty to make such departures therefrom as fairlyfall within the spirit and scope of my invention.

IIaving fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with the body, spent and cap of an oiler, of aspring-actuated follower located in the outer end of the cap which isrotatable independently of it, and containing a stopper or packingadapted to engage with the end of the spout for closing the same wherebythe cap may be rotated for screwing it into and unscrewing it from theoiler without rotating the follower and causing the stopper or packingwith which it is provided to be cut out upon the end of the spout.

2. In an oiler, the combination with the body and spout thereof, of acylindrical cap 40 adapted to inclose the spent, a button-like followerlocated within the outer end of the cap which is rotatable independentlyof it, a stopper or packing located within the follower, and a springinterposed between the end of the cap and the flange of the followerwhereby the cap may be rotated for screwing it into and unscrewing itfrom the oiler withoutrotatin g the follower and causing the stopper orpacking with which it is provided to be cut out upon the end of thespout.

In anoiler, the combination with the body and spout thereof, of acylindrical cap for inclosing the spout, a button-like follower locatedwithin the outer end of the cap which is rotatable independently of it,and having a contracted neck and an annular flange; a stopper or paeking located within the follower in which it is retained by the contractedneck thereof, a spiral spring interposed between the outer end of thecap and the flange of the follower for moving the same outward, andmeans, such as a bead, formed in the cap for limiting the outwardmovement of the follower whereby the cap may be rotated for screwing itinto and unscrewing it from the oiler without rotating the follower andcansing the stopper or packing with which it is provided to be cut outupon the end of the spout.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
